New LEMO 12-way 0B Connector Introduced


LEMO is showcasing its latest products and initiatives at SME 2015, producing even smaller connectors whilst maintaining or improving connector performance, along with products from newly-acquired specialist cable manufacturer, Northwire Industries.

Northwire offer special cables to customer requirements in small quantities and on a fast turn-round, thus complementing the range of connectors and enabling LEMO UK to offer customers complete custom connection solutions, including overmoulded assemblies. Northwire have many years experience of manufacturing cables for a wide range of industries, including Medical, Test & Measurement, Defence, Robotics and Automation. Quality approvals include ISO9001 and AS9100C.

The latest “Tiny Trio” of LEMO connector developments are based around smaller diameter contacts though still having high contact ratings due to the continued use of the unique LEMO contact design, with the inbuilt spring ensuring continuous contact even with high vibration.


Consequently LEMO have firstly been able to squeeze 5 contacts each rated to 1.5A into their tiny 00 series which is only 6mm diameter, making it ideal for communications and other equipment where very small yet tough connectors are required for handling signals. Additionally (on show for the first time at Southern Manufacturing exhibition) LEMO are now able to offer 12 contacts in the 0B series which is only 9.5mm diameter, also 1.5A continuous rated.


The second new range from LEMO is the waterproof T Series, which is based upon the long and widely established B Series connectors, incorporating the original LEMO push-pull latching connection technology and including an inner sleeve and additional sealing to provide protection against water ingress to IP68 level when mated. The 0T Series was the first of the T Series to be made available, and other larger sizes will be at the show for the first time.

The new T Series utilizes the proven high performance contact system and configurations from the highly popular LEMO B Series range, providing a very wide selection of options that can be made available quickly. It is backwardly compatible with the B Series, with the same socket panel hole diameter, which will be of considerable benefit to customers looking to upgrade existing designs as there is no need to change front panel dimensions, and upgraded cable plug assemblies will work with existing sockets.


The third development, the MM Series, is the smallest of the LEMO M Series ratchet coupling connectors, the significantly smaller alternatives to standard military connectors (e.g. MIL C38999) with up to 4 contacts in a ruggedised micro housing.
